BOBBINHOLDER.

SPECIFICATION forming part of Letters Patent No. 745,528, dated December1, 1903. I

Application filed February 17. 1903. Serial No. 143,815. (No model.)

To 0,55 whom, it may concern.-

Be it known that I, HARRY W. SCATOHARD, a citizen of the United States,residing at Bridgton, Maine, have invented certain new and usefulImprovements in Bobbin-Holders, of which the following is aspecification.

My invention relates to bobbin-holders, and

Y has for its object the production of a bobbinholder which will be moredurable, which will not injure the bobbin, and which will securely holdbobbins of different sizes.

In the majority of bobbin-holders now in use the jaws are either pivotedto the body of the holder or are secured thereto in such manner as topermit a pivotal or rocking motion. Holders of this style are not onlyshortlived, but when the jaws are loosely mounted the removal of thebobbin is liable to displace or pull out one or more of the jaws. It isto overcome these disadvantages that the present invention is designed.

In the drawings, Figure 1 is a front elevation showing in dotted linesthe holder mounted on the spindle and the bobbin in place. Fig. 2 is alongitudinal sectional view of the bobbin-holder. Fig. 3 is a sectionaldetail of one of the jaws.

Referring to the drawings, A indicates a spindle; B, a bobbin, (shown indotted lines,) which may be of the form and construction commonlyemployed on mules and spinningframes.

0 is the bobbin-holder, of which the disk 0 forms the bottom plate. Thisdisk is provided with the usual opening (:1 for the spindle and hasformed in the periphery thereof a series of radial recesses orslidev/ays e.

The jaws D are segmental in shape and flare outwardly from a point nearthe bottom. On the lower extremity of the jaw is the inwardlyextendingprojection or arm 'n, which is adapted to enter the recess e in the disk0 and to have a sliding motion therein. On the outside of the jaw andnear the pointwhere it begins to flare outwardly are the grooves 0 forthe spring 0, which encircles the jaws and presses them firmly againstthe bobbin.

of the groove 0, and it will be obvious that by slipping the spring fromthe lower into the upper groove the tension thereof will be increasedand a greater pressure exerted on the jaws. These jaws may be struck indies from a. single piece of metal or may be made up in any desiredmanner.

From the foregoing description it will be seen that my bobbin-holderwill accommodate many sizes of bobbins, that it will be very durable,and, further, that the jaws cannot easily become disarranged.

What I claim is I. In a bobbin-holder the combination with thebase-plate, jaws secured thereto and a spring encircling. said jaws ofmeans for varyin g the tension of said spring, substantially asdescribed.

2. In a bobbin-holder the combination with the base-plate,outwardly-flaring jaws secured thereto and a spring encircling said jawsof a series of annular grooves surrounding said jaws and adapted toreceive said spring, said annular grooves being of (litterent diameter,substantially as described.

3. In abobbin-holder the combination with a jaw having anoutwardly-flaring upper portion and a groove on the outer surface ofsaid jaw having its edges raised above the level thereof, of a secondgroove formed by the upper edge of the first groove and theoutwardly-flaring upper portion of said jaw, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
